Morning,
Which light?
Can you get it on diagnostics?
Why did you fit the new injector harness ?
Cheers

ECU light, never heard of that one.........Is that what it is called in the owners manual?.
I would get it on a decent Diagnostics machine Nanocom / hawkeye / lynx / testbook and have the faults read and cleared then see what happens, To make sure it was read correctly and is a valid fault before doing anything else.

The MIL (which i think the OP means) will come on only for two management reasons on a Td5: crank sensor signal or TP sensor signal failure, it can have missbehaviours if the connection between the instrument pack and ECU on the MIL output is lost or the ECU makes tricks, that warning will not come on for injector fault codes whatsoever

I've also experienced a persistent MIL light when I had a fault in the wiring loom between the accelerator pedal and the ECU. So I wonder whether there might be a wiring loom faulty in this case too.

so it was TP sensor signal failure which is normal to bring on the MIL... a fault in the engine harness can cause that but not oil in the ECU or the injector loom

Yes indeed. I wouldn't expect a mil light with an injector loom fault.
However, with the throttle position sensor or its associated wiring it should in theory show up with a Nanocom or similar.
